Answer:
0.083
Step-by-step explanation:
Numbers of Cube = 6
Faces on coins = 2
Therefore, The total outcomes =
Now the favourable outcome that he rolls a 4 & flips a head = 1
The probability that he rolls a 4 & flips a head = 1
=> The probability that he rolls a 4 & flips a head =
Therefore, The probability that he rolls a 4 & flips a head = 0.083
Answer:
And we can find this probability with this difference:
And in order to find these probabilities we can using tables for the normal standard distribution, excel or a calculator.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
And in order to find these probabilities we can using tables for the normal standard distribution, excel or a calculator.
